Be it knownthat'I, J oHN F. HnMnNWAY,

a citizen of the..United States, residing at New York city, in the county of New York and State of New York, have invented cer-l tain new and useful Improvements in Pressure-Roll Releases for (llothes-Vvringers, of

which the following .is a specification,ref erence being had therein to the accompany" i-ng drawing.

tThlS invention relates to'certal n new and useful improvements in pressure roll release for ciothes wringers, and 1s an lmprovement upon my pressure release as covered in an "application filed by me March 31st, 1916, Serial No. 88,009, the object being to provide a pressure release in which the top bar of 'the' wringer frame carrying the pressure screws can be .released'in order to allow the same tomove vertically a predetermined distance in order to release the pressure on the pressure rolls without detaching the top bar from. thewringerframe.

Another object of invention is to provide a pressure roll release which is 'mounted on the'under side of thetop bar i in such a manner that the same isoutof the way, said release being in the nature of a flat spring :havingsubstantial T-shaped ends codperating V withlslotted members carried by the side bars 'of the frame.

Another and further object of the 1nvenp r lower end is'mo'unted on theplates 14; cartion is to rovide the top bar with an operating meni er in the form of a push k utton which is adapted to be forced downwardly in order to draw the reduced ends ofthe springs in alinement with the reduced .slots of the members carried by the side bars so as to allow the top bar to move vertically. I

Other and further objects and advantages and the novel features thereof the appended claims,

In the drawings, Fig. 1 is a front eleva tion partly, in section of a clotheswringer showing the application of my improved construction of pressure release thereto, Fig.-

is a section taken on the line 2-2 of Figl j showing-the position of the spring on the under face of the top bar. Fig. 3 is an end view showing the spring in position within the slot of the membercarried 'by'theside bars of. the frame, and Fig. 4 is a detail PRESSURE-ROLL nnnnasn rfon cLoTnns-wnmenns.

Likenumerals of, reference refer to like 1 parts in the several figures of thendrawing.

In the application of myimproved construction of pressure 'release for clothes wrmgers,'I show a clothes wringer comprising aframe 1 composed "of slotted side bars 2 connected together at their lower ends 'by'a rod 3 and connecting members 4, and

at their. upper, ends. by a 'movably I mounted top bar 5'. Mounted in the slotted side bars 2 of the wringer-frame are bearings 6 and 7 in which the shafts'8'and 9 of the pressure extends outwardly beyond the wringer frame and is adapted to bedriven by any suitable meanssuch'as a pulley or crank.

' spring supports 8; on which are mounted the rolls 10 and 11' are mounted, the shaft 8 lower ends of thecoil' pressure springs 12 will be hereinafter fully described. The top bar 5 of the wringer" frame is provided with a pressure screw 15 at each end,'and the 'ried by the pressure bar 13 so asto exert a carrying a pressure. bar 13 which is prefpressure upon the bearings of the upper pressure rolls through-the mediuin'of-the The abovedescription is given so marin pressure springs.

application" of-my improved release forlthi s 1 form of wringer can :be clearly understood,

but-of course, my improved releasing'device is capableof being attached to any of the well known wringers now in use in which a movably mounted top bar is employed for carrying the pressure screws.

Secured to the upper endof each ofthe side 'harsQQof the wringerframe is a member 16 which bridges the slotted portion 7 theresf aii ci is provided with a horizontally disposed slot-l7 communicating with a verticall disposed slotv 18 forming a substan-.

tial yinverted -Tshaped opening in the member; the slot '17 being-of a greater width than the slot 18, for the purpose herein-' after'fully described. i

' Slidably mounted on the under side of the top bar 5 is a fiat spring .19 herein shown provided with slots 20 through-which headed screws 21 pass for holding the same in position on the under face of the topbar 5 I in sucha manner that the spring 19 is free to move thereon, and while I have shown the spring 19 slotted and mounted on the top bar 5 in this particular manner, I do not 7 wish to limit myself to any particular mannor of mounting the same, as various other means can be employed for slidably supporting the spring on the under face of the top 'bar without departing from the spirit of my invention. I

The spring 19 is provided with'slotted.

portions in alinement with the pressure screws 15 of the top bar 5 through which.

the pressure screws 15 pass and engage the bearing plates 14 of the pressure bar 13 as clearly shown in Fig. 1 so' as to allow the spring 19 to expand and contract. The ends of the spring 19 are provided with substantially T-shaped heads 22 formed by providing the spring with oppositely disposed notches to provide reduced portions 23 which are of a width substantially the same as the I the central portion of the spring in order to draw the reduced portions of the ends of the width of the slot 18 in order to allow the top bar to move vertically when the reduced portion of the springs are brought into alinement with the slots 18"of the members 16. I

In order to provide means for depresslng spring into alinement with the slots 18, I provide the top bar with a vertical bore 24 'having'an enlarged portion 25 in its under face in which is arranged a nut 26 having a rounded lower face which is-carried by thethreaded lower end 27 of a push button 28, slidably mounted within the bore24 of the top bar 5, said nut being looked upon the push button by -a lock washer 29 as clearly shown'in Fig. '1 in order to prevent the nut from rotating on the push button after the same has been adjusted in position thereon.

-. The operation of the pressure release as exert the proper pressure on the pressure means of the wringer.

In case of an accident, or a foreign object being drawn between the pressure rolls :and it is desired to release the pressuremeans instantaneously,

it is only necessary for the operator tostrike the push button 28 which is provided with an enlarged head so as to force the nut into engagement with the flat spring which bores thecentral portion thereof in order to draw the ends of the spring inwardly which brings the reduced portions 23 into alinement with the vertical slots 18 of the members 16, and

allows the top bar to move a, predetermined distance within the wringer frame which releases the pressure on the pressure rolls. As the top bar ofthe same moves vertically within the wringer frame, the heads formed on the ends of the fiat spring 19 prevent the spring from being drawn inwardly to such an extent that'the top bar would become detached from the wringer frame.

From the foregoing description, it will be 4 seen that I have provided a pressure releasmg devlce'for a clothes wringer in which the pressure means can be mstantaneously .releasedby allowing the top bar to move vertically av sufficient distance to release the pressure means, the movement of said top bar being limited by the vertically disposed slots of the members carried by the side bars of the frame and prevented from being detached by the heads formed on the ends of;

the flat spring carried by said top bar where'-- by a pressure releasing device is provided which releases the pressure means without detaching the top bar from the wringer frame.
